In set theory, cardinal numbers represent the size or cardinality of a set. A set is a collection of unique elements, and cardinal numbers are used to quantify the number of elements in a set. Cardinal numbers are denoted by symbols such as ℵ₀ (aleph-null), ℵ₁, and ℵ₂, which represent the cardinalities of infinite sets. Cardinal numbers are used to compare the size of sets, with ℵ₀ representing the cardinality of the set of natural numbers, for example.

False. Cardinal numbers have practical applications in various fields, including data science, machine learning, and computational complexity.
